A platform is rotating at an angular speed of 1.62 rad/s. A block is resting on this platform at a distance of 0.437 m from the axis. The coefficient of static friction between the block and the platform is 0.720. Without any external torque acting on the system, the block is moved toward the axis. Ignore the moment of inertia of the platform and determine the smallest distance from the axis at which the block can be relocated and still...

A motor gives pulley A an angular acceleration αA = (2 t3) rad /
s2, where t is in seconds. If you are initially rotating at an
angular speed ωA = 15 rad / s, determine the speed and acceleration
of point D when t = 3 s. Point D is on pulley C. Pulley B is fixed
to pulley C and rotates together.
